To all whom it may concern:

Beit known that I, WILLIAM J. WRIGHT, a citizen of the United States,residing at Pittsburg, in the county of Allegheny and State ofPennsylvania, have invented certain new and useful Improvements in Wire-Weaving Machines, of which the following is a specification, referencebeing had therein to the accompanying drawings, forming part of this :ospecification, in which- Figure 1 is a view, partly in section andpartly in elevation, of my improved wireweaving machine on the line I Iof Fig. 2. Fig. 2 is a sectional plan view thereof, indicated by theline II II of Fig. 1. Fig. 3 is a sectional view on the line III III ofFig. 1. Fig. 4 is a horizontal sectional view on the line of section ofFig. 2, illustrating the camoperated clutch mechanism thrown out of enzogagement by which the feeding-rolls remain stationary during theshearing operation. Fig. 5 is an end view of the machine. Fig. 6 is across-sectional view on the line VI VI of Fig. 1. Fig. 7 is a detailsectional view of the knife and its operating mechanism, showing theshearing operation. Fig. 8 is a cross -sectional view through thefeedingrolls, spindles, and shear, on an enlarged scale, illustratingmore fully the construction 3o shown in the upper portion of Fig. 6.Fig. 9 is a detail plan view illustrating the relative arrangement ofthe coiling-guides and the spindles. Fig. 10 is a cross-sectional Viewon the line X X of Fig. 9, illustrating the ar- 3 5 rangement of thespindles and the intervening coiling-guides.

My invention consists of an improved machine for weaving wire intofabric or netting composed of interfitting spiral coils, whereby 4o thefull width of the netting desired may be made at one time of any desirednumber of wires simultaneously and continuously and in one operation.Heretofore in making wirework of this description it has been thepractice to form either a single spiral coil upon a forming-spindle byinterweaving such coils into the last woven coil of a connected seriesor by making two interfltting spiral coils upon a forming-spindle andthen joining pairs of 5o such interwoven coils by a single coil andcontinuing such operation until the required width was obtained.

In the practice of myinvention I employa plurality of spindles 2, havingthe usual spiral grooves 3 3, which spindles are mounted 55 in suitablehousings or frames 4 at such a Vdistance apart as will admit of thelocation loetween the spindles of separate ceiling-guides 5, which forapproximately the full length of the spindle are straight. These guideshave 6o on one side a groove 6, of sufficient size to admit the Wires,but partly closed, so as to not allow the wires to escape outwardly,andv at or beyond the delivery end ofthe spindles each of these guidesis formed into a spiral 7 65 of the same pitch and relative position asthe spiral grooves 3 0f the spindles, the groove 6 of the guides beingmaintained on the inner side, as shown.

By reason of the close arrangement of the 7a pairs of spirals formed onthe spindle 2 to the next adjacent pair similarly formed it will be seenthat the spiral guide 7 may be located as to the alternate oppositespiral loops of such pairs Without interference with the forwardprogress of the coils, whereby when the independent spiral coils 8 arefinally delivered from the ends of the guides 7 they will travel forwardin the same relation to the coils 9 10 from spindles 2 and will inter-8o engage with such coils, as by reason of the close proximity of eachindependent pair 9 10 sufficient clearance is allowed for freeengagement and interaction, and it will be seen that such assemblage andinteraction of the coils will be continuous throughout the operation.The forward feed of the wire is accomplished by means of upper and lowerfeed-rolls 11, mounted in suitable housings 12, the rolls being gearedtogether by toothed gearing 13, 9o so as to operate simultaneously andat uniform speed.. Motion is transmitted to one of the rolls through atoothed wheel 14 in engagement with asimilar wheel 15, mounted upon themain shaft 16 and adapted to be in- 95 mittently thrown into gear withsuch shaft by means of interiitting clutch members 17 18, the clutch 18being automatically operated by means of lever 19 in engagement with itand operated by cam 20 on shaft 2l. The loo shaft 21 is rotated at slowspeed through pinion 22 on' its outer end in mesh with a driving-pinion23, mounted upon the outer end of a spindle 24, which is adj ustably setin the segmental slot 25 in the housing, which permits the spindle 24 tobe set toward or from the main shaft 16, so as to permit of theinsertion of gears of diiferent sizes, so as to vary the relative speedof the main shaft and feed-rolls and shaft 2l, by which the shearingmechanism is operated, whereby the machine may be set to cut offdifferent lengths as desired. Power is imparted to the driving-pinion 23through toot-hed wheel 27, mounted upon spindle 24, preferably securedto pinion 23, the pinion 27 beingin mesh with driving-pinion 28 on theopposite end of the main shaft 16. Such main shaft is driven by belt orother connections through pulleys 29 or other suitablyconnectedmechanism from any desired source of power.

Upon shaft 2l, carrying cam 20, are mounted cams 30 on the inside of theend bearings of the shaft, which cams for three-quarters of theirperiphery are of uniform diameter, the other quarter being formed intothe cam projection 3l, which projection in the rotation of the camdepresses the end 23 of lever 33, pivoted at 34: to the frame andprovided with a pivotally-connected pitman 35, attached to and for thepurpose of operating the knifebeam 36, mounted in vertical slideways ateach end of the machine. The lever 33 is provided with a counterweightw, by which the depressing action of the cam is reversed and theshear-beam raised.

The construction of the cam, lever, and connections therefrom to theknife is, as shown, the same at each end of the machine to insureuniform action.

The shear-beam is provided with knife 37, which slides upon the outerface of stationary shear 38,thr0ugh openings 39 of which the wovennetting passes outwardly from the weaving-spindles. l

The clutch 18 is held in engagement with the member 17, so as totransmit rotatory movement to the rolls to feed the wires duringthree-fourths of the revolution of shaft 21 by reason of the relativearrangement of the cams 20 and 30. The clutch is thrown out of gearduring the downward travel of the knife, so that the feeding-rollsremainstationary for one-fourth of the revolution of shaft 21 or untilthe shearing action is completed, the shearing-knife being raisedsimultaneously with the renewed clutching engagement produced by cam 20.As thus constructed, the individual Wires are fed inwardly between therolls to the spindles, and the operation is continuous and automatic,the rolls feeding forward the desired length of netting, which issheared off at suitable intervals, as I have described, without furtherattention from the operator than from time to time to renew wire to thespools (not shown) as the same become emptied.

the skilled mechanic without departing from my invention, since I do notdesire to be confined to the specific construction as shown anddescribed, but to include all such changes and variations as are withinthe scope of the following claims.
